Merge Videos

Concatenate two or more video clips into one file. Drag-reorderable, optional resolution normalization and audio join fade.

What it does

Drop two or more video clips, drag them into the order you want, pick an output container (MP4 or WebM), optionally normalize resolution if the inputs are mixed, and the tool concatenates them into a single file.

Join fade applies a linear fade-in to each following clip's audio so cuts don't pop. Video clips concatenate end-to-end; mixed-resolution inputs are stretched to match the normalize target.

How to use it

  1. Drop multiple clips — Drag two or more files in. Each clip appears in a numbered list with up/down/remove controls.
  2. Reorder if needed — Use the ↑/↓ buttons. Order matters — the merged file plays them top-to-bottom.
  3. Normalize and fade joins — Pick 'Match first clip' for fast same-resolution merges, or force 1080p/720p/480p if the inputs mix. Join fade seconds apply to audio.

When to use it

Stitching screen recordings

Two tries of the same tutorial? Concatenate with a 1-second audio join fade between them.

Mini-compilations

Holiday-clip compilation for the family — drop ten videos, set the order, get one file.

Multi-take edits

Trim each take separately with the Video Trimmer, then merge the keepers.

FAQ

What happens if my clips have different resolutions?
Without normalization the encoder picks the first clip's dimensions and stretches the rest. With normalization, all clips are re-encoded to your selected size.
Does join fade affect video?
No. It is audio-only. Video clips switch hard at the boundary.
